451: More type inference for more binary expressions r=flodiebold a=marcusklaas
Implements more of https://github.com/rust-analyzer/rust-analyzer/issues/390. Just works for primitive (numeric) types for now.
Found an issue where `let x: Ty = expr;` doesn't actually propagate the type information unless `Ty` is primitive and numeric. I'll open an issue for this.

450: Implement autoderef for field accesses r=matklad a=flodiebold
Which means we now get completion for fields e.g. in `&self` methods :)

442: WIP: indent on typing dot r=matklad a=simonvandel
Fixes#439.
The unit test passes, but I can't seem to make VS code perform the action. The existing action on "=" doesn't work either on my end either though.
I didn't add any smart way of detecting the current indent level. Any ideas how I would do that?

446: Use HIR Expr for type inference r=flodiebold a=flodiebold
Now we can reuse the type inference inside a function when typing whitespace etc. :)
The order of the lines in the type tests changed a bit, which I'm not sure why, but there are no actual changes in the inference results.

440: Implement type inference for boolean operators r=flodiebold a=marcusklaas
Tried implementing the easiest part of https://github.com/rust-analyzer/rust-analyzer/issues/390. Hope this is somewhat close to what the intent of the issue was. Found it surprisingly easy to find my way around the repository - it's well organized!
Very grateful for any pointers.

429: Reorganize hir public API in terms of code model r=matklad a=matklad
Recently, I've been thinking about introducing "object orient code model" API for rust: a set of APIs with types like `Function`, `Module`, etc, with methods like `get_containing_declaration()`, `get_type()`, etc.
Here's how a similar API might look like in .Net land:
https://docs.microsoft.com/en-us/dotnet/api/microsoft.codeanalysis.semanticmodel?view=roslyn-dotnethttps://docs.microsoft.com/en-us/dotnet/api/microsoft.codeanalysis.imethodsymbol?view=roslyn-dotnet
The main feature of such API is that it can be powered by different backends. For example, one can imagine a backend based on salsa, and a backend which reads all the data from a specially prepared JSON file. The "OO" bit is interesting mostly in this "can swap implementations via dynamic dispatch" aspect, the actual API could have a more database/ECS flavored feeling.
It's not clear at this moment how exactly should we implement such a dynamically (or if we even need dynamism in the first pace) swapable API in Rust, but I'd love to experiment with this a bit.
For starters, I propose creating a `code_model_api` which contains various definition types and their public methods (mandatory implemented as one-liners, so that the API has a header-file feel). Specifically, I propose that each type is a wrapper around some integer ID, and that all methods of it accept a `&db` argument. The actual impl goes elsewhere: into the db queries or, absent a better place, into the `code_model_api_impl`. In the first commit, I've moved the simplest type, `Crate`, over to this pattern.
I *think* that we, at least initially, will be used types from `code_model_api` *inside* `hir` as well, but this is not required: we might pick a different implementation down the line, while preserving the API.
Long term I'd love to replace the `db: &impl HirDatabase` argument by a `mp: &dyn ModelProvider`, implement `ModelProvider` for `T: HirDatabase`, and move `code_model_api` into the separate crate, which does not depend on `hir`.
@flodiebold you've recently done some `Def`s work, would do you think of this plan? Could it become a good API in the future, or is it just a useless boilerplate duplicating method signatures between `code_model_api` and `code_model_impl`?

441: hir::Expr r=matklad a=flodiebold
Still a bit to do, but I already adapted `FnScopes` and thought I'd get feedback already.
